Neodymium Magnet

(also called：NdFeB magnets, neodynium magnets, rare earth permanent magnet) Neodymium magnets, also known as NdFeB magnets. It is the third- generation rare earth permanent magnet. Due to the extremely high magnetic properties and moderate production cost, neodymium magnets are the most popular rare earth permanent magnets worldwide.

OUR EXPERTISE

New Technology

Grain Boundary Diffusion

Grain boundary diffusion technology is to use surface coating, magnetron sputtering, vacuum evaporation, electrophoretic deposition, etc., to form the thin layer of Dy or Tb on the surface of thin sintered NdFeB magnets with a thickness of less than 9mm, and then pass through proper heat treatment and tempering treatment . The intrinsic coercivity of the neodymium magnets is greatly improved after that. The method helps to reduce the use of heavy rare earths, thus reduce the manufacturing cost, and can also produce high-performance magnet that cannot be achieved by normal processes.

Laminated Magnet

Laminated magnet assembly is featured of small vortex , while remaining the same or even higher performance as normal magnet assembly. The laminated neodymium magnets could be used as rotor magnet of motor, especially in electric car. Thus it is more and more applied in insulated stitching magnet components .

Application

Automobile industry

Consumer electronics

Industrial Motor

Household electrical appliances

Automobile industry: Automobile industry is one of the most widelyapplication of sintered neodymium magnets.There are more than 30 spare parts in a vehicle where neodymium magnets are used. Approximate 2.5Kgs high-performance neodymium magnets are consumed for each fuel vehicle and 5kgs neodymium magnets for new energy vehicle. The demand of high-performance neodymium magnets increases fast every year. Automobile industry will become the biggest application area when all fuel vehicle is replaced by new energy vehicle.

Consumer electronics:Electronic product is one of the traditional applications of high-performance neodymium magnets. Taking smart phone for example, there are more than 10 spare parts where neodymium magnets are used, for example microphone, micro speaker/receiver, vibration motor, wireless charger,Bluetooth earphone, phone camera focusing,sensor, to name just a few.With the advancement of science and technology, more and more accessories in smart phone are made with neodymium magnets.

Industrial Motor: neodymium permanent magnet motor is more and more popular due to high efficiency, small size,low weight and eco-friendly. The energy consumption could be reduced significantly compared with ferrite magnet motors. It is the trend to replace the ferrite magnets with high-performance neodymium magnets in industrial motors.

Household electrical appliances:Nowadays, more and more electrical appliances with fixed frequency technology are replaced by frequency conversion technology due to energy saving and eco-friendly. Taking air conditioner for example, the energy consumption of frequency conversion compressors is reduced by more than 30% compared with fixed frequency compressors. What is more, it can reduce noise and prolong the working life of air conditioner.
